Title: Preventing method of aging change in resonance frequency of piezoelectric device
Inventor: TANAKA MASAKI
IPC: H03H3/08
Filed: 1983-04-08
Abstract: PURPOSE:To prevent the aging change in resonance frequency by vapor-depositing magnesium fluoride on the interdigital transducer electrode of a piezoelectric device or sticking surface between it and a reflector. CONSTITUTION:The interdigital transducer (IDT) electrode 2 is stuck to the surface of a piezoelectric substrate 1. Then, magnesium fluoride 9 is vapor- deposited on the IDT electrode 2 or the surface of the piezoelectric substrate where the reflector 3 is stuck to specific thickness. Therefore, the inclination of a decrease in resonance frequency considered as results from the condensation of an adhesive for fixing the piezoelectric substrate to a holder is canceled by the inclination of an increase in resonance frequency due to an aging change of vapor deposited magnesium fluoride.

Title: Current/current converting circuit
Inventor: NAGANO KATSUMI
IPC: G05F1/56
Filed: 1984-03-31
Abstract: PURPOSE:To compensate influence to a transmission ratio due to the variation of the characteristics of photocouplers by electrically separating input and output terminals by using two pairs of photocouplers having the same characteristics. CONSTITUTION:If it is supposed that the input current of an operational amplifier A and the base current of a control TR 17 can be neglected, the output current IC of a photocoupler PC2 is equal to input current IIN. On the other hand, current flowing into a light emitting diode 16 in the photocoupler PC2 becomes IF=IC/K2 (K2 is the transmission ratio of the PC2). Consequently, IOUT=IIN.K1/ K2 is formed. Even if the characteristics of the PC1 and PC2 are changed when the transmission ratios (characteristics) of the PC1 and PC2 are equal, the variation is compensated each other. Thus, the influence to the transmission ratios due to the specific variation of the photocouplers can be compensated.
